Don't buy Philips bulbs on eBay. Too many fakes out there.

D2S is available genuine pair from hidbulbzrus.com for 74 shipped.

But to be certain its the bulb id swap it side to side to be sure the ballast is good on that side.

And I think it goes without saying to replace the pair if is is the bulbs
